I used those 2 threads trying unlock my L720, I followed everything up and It went smoothly It worked with (Simple mobile & Straight talk att sim card) but I was not getting a constant service, decided to go back to sprint and then, just trying to go back to stock firmware!
I am getting "Firmware upgrade encountered an issue.." in Odin every time that I try MDC, MK2 Stock firmwares says "FAIL! (Auth)" ?????
The only tar that is working is MDC modem tar found on the 1st thread used to downgrade modem to MDC, even though I was in NG2 which is the latest i was stock and rooted!
Then the phone boot up there's no sound no WiFi touch problems or is it the phone is really slow!?. I did a factory reset and nothing!
Another thing, but I noticed this since unlocked it! there is a picture too! Baseban and build are different!
Please any help would be appreciatte it!1 Thank you!
I have really made a mess trying to fix it myself.
I will write the current status and at the bottom what I've tried so you can skip

22 Apr KST 2016
now the sim card works in other phones and when I remove it the device registers it is SIM CARD REMOVED but when I put it back in nothing happpens, and mobile networks settings is gone
*I started in stock 5.1.1 (MADE NANDROID BACKUP OF EVERYTHING INCLUDING EFS) and flashed twrp via odin > (everything still working)
*flashed XtreStoLite 2.4 (5.1.1) via twrp > (everything still working)
after several months
*flashed new 6.0.1 bootloader and modem via odin and tried to flash XtreStoLite 3.0 (6.0.1) via twrp > got stuck in bootloop...
*used smart switch to go back to stock 6.0.1> Everthing was OK until about a month later the phone suddenly restarted and doesn't recognize the sim card
* I tried factory reset
* I tried samsung but they gave it back saying I've tripped my knox flag
*I flashed 6.0.1 XtreStoLite bootloader, modem and TWRP again via odin
*I flashed XteStoLite 3.3.1 (6.0.1)
*I tried restoring from the first nandroid (stock 5.1.1 from the begining) and got stuck in bootloop again.
*reflashed XtreStoLite 3.3.1 (6.0.1) and tried restoring only the efs. still doesn't work.

I saw some threads talking about octoplus box but I still have my efs Backed up my and SN and IMEI still show up.
Please help me I am here I am willing to learn and search online. I've tried everything i've found online.
Hi.
Try to use Smart Switch > Software Update and Initialization to recover your firmware, hopefully you get your network back.
Tell me what happens, gl.
Sent from my SM-G920F using XDA-Developers mobile app
almost same thing on a long thread here, no solution so far:
http://forum.xda-developers.com/galaxy-s6/help/g920f-network-issues-t3291903
I am seriously considering it could be sim reader issue, or some cold solder somwhere on mbo.
My IMEI was also showing in settigs, but when dialed *#0011#, in stack 1, there was "IMEI NG", after write cert operation via octoplus, it says IMEI OK now, but NO SIM, and no mobile networks menu still.
Same like you SIM is detected when inserted or removed, and phone offers restart to access mobile networks, but after restart nothing changes, KNOX tripped by previous owner, phone was in three 3rd party repair shops, where they made even bigger mess than it was, when I brought it to them.
i had the same issue when i upgraded to mm so i sent to shop they had to downgrade it to 5.1.1 and use octobox to fix it
Thanks for replying Legend.
But even though I did the software Initialization in smart switch once before it is not working for me now.
I've tried twenty time while reinstalling and restarting the pc I even tried a different pc I get the same error message every time. "failed to run firmware upgrade unknown error occurred".
any other thing to try?
you could try to restore that backup you have, from when everything worked and then flash 5.1.1. bootloader and modem for that csc via odin before rebooting
According to Smart Switch with your sn it is ILO so you need 5.1.1 bootloader and modem from ILO 4 file fw package.
*I just managed to flash stock 6.0.1 via odin (even though It failed at hidden.img... it boots normally) still no sim card tough.
*I realized that maybe all of this happened because when I flashed stock via smart switch for the first time I didn't have my original s/n so I put one from the internet and it wasn't my region.
meaning I flashed stock of UK and it still worked for a month or so, so that's weird...
*Thank you brenner that is a good idea and I will try now
question how do I extract the bootloader and modem out of the fw? I just open the tar archive and take the boot.img and modem.bin files and flash them as is?
nvm found a guide

There are .tar-s which are single file, and 4 files, the ones with 4 files has separate bl/modem
btw, isnt sn written on back of the phone, along with IMEI?
OK, I've flashed the nandroid stock 5.1.1 (LMY47X.G920FXXU3COJ1) and its bootloader and modem from sammobile.. still doesn't work!!
How can this be? everthing is EXACTLY the way it was when it was working!
and no, my model at least doesn't have the S/N and IMEI written at the back, and I didn't keep the box
any other suggestion anyone?
*also there are so many post in subject if I ever find a solution I will make a guide.
-bump-
still no solution..
I've flashed back to current stock ILO...
Meanwhile looking for a lab with octoplus box, still would love solving this at home
At home or not, I would like to solve it too
Bought a second hand S6 the other day and was working perfectly fine until I carried out the update. Now on 6.0.1 and am getting the exact same problem, my SIM works in every other phone. Has anyone found a solution for this?
Not that I know of, except hw replacement, which cost as a used phone with 1+ years of warranty (6 months warranty on motherboard after replacement, on motherboard only)
But I am willing to donate to whoever finds a solution for it.
No i think your problem is a S/W problem, i have 2 G920F with this problem, one of them is 3 binary and another is 4 binary FW, now i work on it if i can solve this problem i told you here.

I got this e3 that i flashed 3 different stock roms, and i can't get sim card to work on any of them. With or without sim installed i get a failed check picture and i can't use sim, tho other things work just fine. I have tried a central european rom, a rom made for my counrty, but im not sure weather the sim card is from that operator the rom is made for.
I took the phone form a frined to try and fix it since it was stuck in boot loop, so i've handled that and i'm not sure how to fix this :crying:
The roms we apropriate for the model, d2203, used the both latest one and the one before.
Did you resolve this?
I found that if you run flashtool on pro mode it will allow flashing of simlock.
I don't know exactly what's that but I hope it (and google) helps you
I am facing a problem. I was experimenting with THE GALAXY PROJECT rom. I turned on developer options and removed oem unlock.I installed twrp for hero lte and did format partition instead of wipe and installed the galaxy project rom. It worked fine but then I revereted to my stock firmware with ODIN. I noticed that I am not able to call any one. I thought i had installed England Firmware on Indian firmware as I faced that problem, so I downloaded the indian firmware again but again it was working on england firmware. I can say this because it was using upday instead of samsung briefing. I thought its a wrong rom again and to atleast make calls installed herolte rom. Same problem. Call ends immediately. My sim works fine in another phone. Any other sim stops calling in my phone.
Can any one suggest a solution of what might have happened.
I just booted into recovery and it mentions there herolte recovery.
Any solution.
Post Note - Rom were fine. Only calling and sending sms is not working. I can receive a text and can use internet over LTE. System cannot read sim phone number in hardware diagnostic. I cannot open aditional setting in phone as it says that error reading sim card.

Reinstall original England rom using Odin. And then install twrp and again install TGP or any other OREO rom you like.
Don't forget to format data after installing tgp for the first time.
Also boot up and reboot once after clean flashing with Odin.
Then flash twrp.
P.S try flashing csc selection by tkkg it may help.
Also which rom are you using nougat or oreo?
I have used Oreo as well as nougat. Problem persists.
Only my current operator aim are not working and rest of the sim are working fine. Service center haa asked me to get motherboard changed.
I was installing indian rom. Now even samsung knox related apps are not working.
So basically you want me to install tgp again and twrp after that and again went back to stock after that.
Do you have any idea why this problem could have been causes. Can rooting mess with physical hardware of phone?

Okay then phone and SMS probably won't work, cause I guess the Indian version is still a nougat but the England one in oreo both your modem and firmware would have been updated and it's not possible to go back, so I suggest you stay with TGP for a while until official oreo arrives in India.
Or else don't use phone or messaging ?
Hi ,
I recently flashed my Galaxy S8+ with Hades ROM which is a ONE UI based ROM .
Everything works fine but sim card is not getting any signal or just shows " not registered on network" sometimes.
But it do work sometimes when connected to WiFi n when WiFi calling is enabled , but I can't use my mobile data or calls from my carrier network.
THE PHONE BASICALLY HAS FEW ISSUES BEFORE FLASHING NEW ROM .
1 ) It was bought from UAE and it was already rooted when I got it .
2) Attempt to flash stock ROM failed everytime cz the SIM card was not detected even when it was in stock ROM itself.
3) so many try with different versions of Odin and different versions of Stock firmware , it did not work .
Please give me some fix .
(NOTE) : SIM card is working very fine but the issue is with the phone itself.
What is so "secret" about this topic, that no one of the experts likes to talk abaout it and help us out? So many have this problem. Even though for those like me who have a stock backup auf EFS and Baseband. If somebody would be so kind to send a pn with further hints would be very kindful. Thanks a lot folks.
I had the same problem after flashing the stock ROM, but i just can't find help with this problem.
I gave up and bought a new phone.
